The immigration proposal outlined Monday by a bipartisan group of senators is intended to create a new system in which border security is enhanced while those who are in the United States illegally get a chance at a green card.

• Increase use of unmanned aerial drones and other surveillance equipment.

• Create “entry-exit system” to track temporary visa holders and ensure they leave the country as required.

Path to Legal Status and Citizenship

• Require current undocumented immigrants to pass a background check, pay fines and pay back taxes before earning “probationary legal status” that allows them to live and work in the United States.

• Mandate that probationary immigrants “go to the back of the line” as they apply for a green card.

• Require probationary immigrants to pass another background check, pay taxes, learn to speak English, go through civics education and prove they have worked in the United States before getting a green card.

• Require that border security enforcement measures be completed before green cards are given to those on probationary status.
